.application filed March 9, 1920. Serial Nol 364,561.1.-

To all' whom it may concern Be it known that EUGENE L. BARNES, ya

citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, has invented certain new and useful Improvements in Fuel-Stoking Structures, of which the following is a specifica- 'ion, reference being had therein to the ac companyingdrawing. io

This invention broadly relates to fuelstoking structures and has more particular reference to means for maintaining certain instrumentalities of the structure in a rela-- 1tively cool condition during action thereof. l5

In an application filed by ine on April 7, 191,9, Serial No. 267,996, there is disclosed an automatically-operated fuel-stoking apparatus; and, as there revealed, this apparatus includes a hopper, a conduit, a nozzle, and a fuel-distributor or baille hingedly mounted on the nozzleA and adapted to be actuated successively to open and restrict passage through the nozzle. l

In practice, by reason of the fact that the nozzle and baille are disposed within a zone of high tempcralure, considerable difficulty has been encountered in preventing rapid destruction or deterioration of these parts, and

particularly the baffle, by reason ofthe intense heat arising from the associated, furnace. Various expedients have been proposed to remedy this difliculty, including the making of the baille of heat-resisting inaterials, such as carborundum and the like; but, while such materials will function to the end desired; yet even they are, in time, 'affected by the heat and either crack or are otherwise injured. As a result of considerable experimentation, I eventually discovered that by circulating a cooling fluid through the baille and, if desired, through the nozzle, these parts will be unaffected by the heat, no matter how intense it maybe. ln Figs. ll, l2 and i3 ofmy said pending application, l have disclosed a fluid-circulating system for coolingv the nozzle and battle; and the structure herein disclosed is an improvenient upon that there revealed.

VGenerally speaking, the structure of the present application involves a nozzle provided with a fuel passage and with afinidi'eceiif'ing channel, operatively associated with a baffle or fuel distributor swingingly mounted on the nozzle for successivelyopening and restricting the fuel passage, the

ei'nbodiincnt of thel invention, though it is to be understood that, inasmuch as this structure may be variously modified, such variations are within the spirit of the invention.

In these drawings:

Fig. 5 is a view in vertical cross-section on the line 5;-5, Fig. 2;` and Fig. 6 is a view in horizontal cross-section on theline 6 6, Fig. 2.

Referring to vthese drawings, it will be noted; thatthc reference numeral l desigtos, generally, a hopper forming a `component of the automatic fuel-stoking appa-V us disclosec my rementioned applidesigna-tes' a chamber or conduit -r ...ted with the hopper, 3 designatesv a` designates an associated fuelinutor or baille. lt is to be understood the nozzle is mounted in the wall ofl j inace (in general) so that its inner end fvl'the baille are within the heat-produc- `iamber of the furnace. .1 .cferably and as shown, V`the nozzle in this instance comprises two companion elements c, 5, these being adapted to be secured to .ether as by bolts 6.and 7; and, when thus ciated, a eenL al fuel passage 8 is met, this being in communication with the'end ofthe conduit 2, as shown in Fig. 2.

une ia i icoV Through this passage is to be projected a vbodyof fuel that is to be distributed over the tire-bed by the baiiie Ll, the latter being, to this end, provided with a Jruel-spreading extension or surface 9 on its inner tace.

k'Each oi the nozzle-elements 5 and 5 is provided Vwith a longitudinal channel 10 and 11 of any appropriate form and dimensions. V Leading into the channel 10 isf a supply pipe 12; and leading` out oi1 the ebannel i1 is a discharge pipe 13the latter preferablgbeing provided Vwith a valve 14 to control the low of liquio through the systeni, it 'being understood that Vthe supply pipeV 12 receives its iluid 'from any Suitable source or" supply, such as a water system operatingunder, say, iiity to seventy-five pounds pressure; whereas the pipe 13 may extend to a hot well (not shown). from which the boiler water supply is taken. The

` oontrollvalve 14, being placed on the dis- Y elements and, thus, the

charge pipe, is preferably closed a suilicient amountto supplyv the required amount f v off water to the nozzle and baille.

llncompassing each of the trunnion-extensions 15 of tie baille is a gland 19 vadapt- -d to hold packing 2O in place between the trunnionextension and the nozzle. .As clearly shown in Figs. 3 and 6, the trunnionloxtensions 15 are fore-shortened somewhat to provide a spare 21 between their ends and the channel walls of the nozzlepassage in each in communication,

trunnion-eitension ne.:v 10o aces S21 being;` a 'continuation oi? these chanthence into the space 21 and through the i 16 in the trunnion-extension, from which it passes into the channel 17 at the it Vpiunpage vwere necessary or advisable "h the space 2l, with either the chan` r 11 in the nozzle-elements; said lett side oi? the baille (as viewedY in Fig. 6) thence the lower end of the partition the baille and into the channel 17 `on e right hand side of the baille; iiowing ce in through the passage 16 of Ythe t iii-extension; andV thence .nnei lo in the nozzleelement 5a; intothe pipe which leads, as ione( to a hot well or other point e not shown. mh iiuid is indicated byarrows in Fig. 6. y
